How Much Does It Approximately Cost To Replace A Furnace Flame Sensor?

Does your furnace kick on and run for a short period before shutting off again, possibly several times before finally shutting down and ceasing to function? If that’s the case, a filthy flame sensor could be at fault. A filthy flame sensor is one of the most prevalent furnace problems and can be caused by a number of factors. If left unattended, you may lose heat, and gas may leak into your home, posing a hazardous risk to your health.

What Is A Flame Sensor?

A flame sensor is a device that detects the presence of fire. Every furnace includes a flame sensor. It is a tiny metallic rod that is positioned directly in front of the flame to verify if one exists in a furnace.

It’s essentially a safety feature that ensures the furnace will only operate if a flame is present. If the furnace is turned on, but there is no flame, there may be a gas buildup that could be harmful. If the sensor does not detect a flame, the furnace will be turned off automatically.

Many systems have the capability of shutting down three times before triggering a complete system safety cutoff, having left you without heat. In this case, always seek a professional HVAC repair Tomball TX.

What Causes A Clogged Flame Sensor?

An unclean flame sensor is a disaster waiting to happen. A prevalent reason for a clogged flame sensor, though, is that it is simply filthy. Because it is a sensitive sensor, any dirt or carbon accumulation could lead it to fail. The majority of people keep their furnaces in the basement or laundry room, which can generate a lot of dust. This dust may adhere to the sensor, leading it to become dirty and your furnace to shut down.

What Can Be An Estimated Cost?

The most prevalent cause of a furnace breakdown is ignitor failure. Dirt can build up inside ignitors if they aren’t maintained properly, eventually shorting out the circuit system and ruining the entire HVAC machine.

Most ignitor replacements are done as an emergency service, so expect to pay around $400. They will cost around $200 if it is done during regular maintenance service.

Likewise, flame sensors can become too dusty and malfunction, but a thorough cleaning can restore them. However, if it’s too late and you need to replace the flame sensor, expect to pay between $80 and $250. Look for an ideal heating replacement Tomball TX, and get that professional help for your flame sensor issues.
